First Aid & Prevention

First 30 Minutes

  • • Immediately remove all remaining plant material from the cat's mouth and living area if ingestion is confirmed or suspected.
  • • Rinse any visible pollen off the cat's fur, paws and face to prevent secondary ingestion via grooming.
  • • Collect a sample of the ingested plant for veterinarian identification, and do not induce vomiting unless explicitly directed by a vet.

Contact Vet Immediately

  • • Any suspected or confirmed ingestion of any part of a Rubrum Lily by a cat, even if no symptoms are visible.
  • • A cat exhibits vomiting, loss of appetite, lethargy or increased urination after possible exposure to the plant.
  • • A cat has visible lily pollen on its body or has been near a Rubrum Lily plant or flower arrangement.

Prevention

  • • Keep all Rubrum Lily plants, cut stems and flower arrangements containing lilies completely out of reach of cats, including elevated surfaces cats can jump to.
  • • Wipe up any fallen lily pollen immediately to avoid accidental ingestion by cats.
  • • Avoid bringing any Lilium or Hemerocallis species plants into households with resident cats.

Treatment & Prognosis

  • • Administer early intravenous NaCl fluid therapy at 2-3 times the maintenance requirement within 24 hours of ingestion, continued for 1 to 3 days.
  • • For cats in the anuric phase of kidney failure, peritoneal lavage, peritoneal dialysis or hemodialysis is required.
  • • Provide appropriate decontamination and symptomatic supportive care per standard veterinary emergency protocols.

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Cat: Extremely high toxicity: even small ingestions can lead to acute kidney failure and death if not treated within 24 hours of exposure
Dog: No known toxicity: ingestion of any part of the plant does not cause adverse health effects per available data
Horse: No known toxicity: ingestion of any part of the plant does not cause adverse health effects per available data
Confusion Risk

The following plants look similar and may be confused:

Other Lilium species Lilium spp.
Visually similar to Rubrum Lily with overlapping flower and growth morphology; all species share the same severe toxicity risk to cats
Orange Daylily Hemerocallis fulva
Similar flower shape and growth habit to Rubrum Lily; also carries severe, potentially fatal toxicity for cats
Yellow Daylily Hemerocallis lilioasphodelus
Comparable appearance to Rubrum Lily flowers; is also extremely toxic to cats, with the same kidney failure risk
